This is the Mowitz ("More widgets) library.

The project's goal is to create a library of widgets for X applications to use. The widgets have been snarfed from various sources and are all open source (GPL or MIT licenses).

Available widgets

• Animator
• Canvas
• Check
• Combo
• Frame
• Handle
• Html
• Image
• ListTree
• Notebook
• Richtext
• Rudegrid
• Ruler
• Slider
• Spinner
• Tabbing
• Table
• Tabs
• TextField
• Tooltip
• VSlider

And a complete menu kit.

The original reason for creating this library is that the Athena widget set lacks a lot of widgets that would be useful, and many of the existing widgets leave a lot to be desired in appearance and behaviour.

Once upon a time there was a project called the Free Widget Foundation. It started out with goals similar to those of Mowitz, but later turned into a project to create a complete, standalone widget set. That is not something that will happen here.

Namespace

All external symbols are prefixed with "Mw" in order to avoid name space clashes with other libraries. So for example, the spinner widget is called MwSpinner.

Applications using Mowitz

Since most of these widgets were previously distributed with Siag Office, it is natural that the upcoming release of that package will use (and require) the Mowitz library.

Many existing X applications can be trivially updated to use the widgets in the Mowitz library.

Utility routines

In addition to the widgets themselves, Mowitz includes several utility functions that are used within the library, but useful to application writers as well. The functionality includes:

• Loading and caching pixmaps
• Allocating and caching pixel values

Mowitz à la carte

It is possible to pick and choose among the widgets within Mowitz. Normally there is no reason to do so, but it can be a way to add a single widget to an application without having to depend on another library. It can also be a way to avoid licensing issues.

To do this, copy the MwUtils.c and MwUtils.h files to the application, plus the files for the widget. All widgets use the routines in MwUtils, so it must always be included.

Some widgets are subclassed from other widgets in the library. The Handle widget, for example, is subclassed from Frame. In that case, both widgets must be included.

Widget hierarchy

Names in brackets are Intrinsic widgets, not part of Mowitz.
